SHAFT-TUG.

SPECIFICATION forming part of Letters Patent No. 500,441, dated June 27,1893.

Application filed March 23, 1893. Serial No. 467,296. (No model.)

To all whom t may concern.'

Be it known that I, WILLIAM F. SWEET, residing at Webbs Mills, in thecounty of Chemung and State of New York, have invented certain new anduseful Improvements in Shaft-Tugs, of which the following is aspecification.

Shaft tugs or thill loops are subject to rapid wear, by reason offriction with the shafts or thills, and therefore frequently require tobe replaced by new ones, While otherportions of a harness remain strongand serviceable.

I have devised a shaft tug whose inner or wearing surface may be changedin position so that a fresh or unworn surface is brought into contactwith the shaft, making as it were, a loop or tug with changeable bearingportions, so that as one portion thereof becomes worn, such portion canbemoved out of contact with the shaft, and an unworn portion of the tugstrap brought into position to support the shaft.

My invention consists in the peculiar construction and arrangement ofparts as will hereinafter be described, and claimed, reference being hadto the accompanying drawings, in which- Figure lis a perspective View ofmy improved shaft tug. Fig. 2 is a central longitudinal section of thesame. Fig. 3 is a perspective view of the keeper. Fig. 4 is aperspective view of the strap,and Fig. 5 is a section ofthe same withthe strap in its reversed position.

In the drawings A indicates the reversible, detachable leather strap,which when folded and joined as shown in Fig. l forms the body of theshaft tug.

B indicates a metal loop or link member connected with the bottom of thetug body, to which is connected the end c of the girth strap C.

D indicates the buckle, and E a detachable l keeper connected with thebuckle tongue, and

arranged in connection with the strap A as hereinafter described.

The strap A is provided with one or more holes in each end, as indicatedby a a2 and a series of holes a3 about centrally thereof.

The manner in which the strap A is folded and joined will be bestunderstood by reference to Fig. 2 of the drawings, it being folded inthe following manner.

The end l of the strap A, is first connected to the buckle, the tongue dof which passes through one of the holes a. It is then passed throughthe eye b of the loop B. At this point it should be stated the keeper Eis secured to the buckle, it being provided with an apertured tongueportion e through which the tongue d of the buckle passes as shown, thekeeper body proper being arranged to extend in an outward direction.After the keeper is put in position in the manner stated, the free endof the strap A is folded back-upon itself and passed through the buckle,the tongue d at this time passing through one of the central holes a3.It is then passed down and through the eye b ot' the loop B, then backupon itself again and its free end 2, passed through the buckle D, thetongue at this time passing through one of the openings a2. The skirtstrap F is then connected with the buckle D and its end passed throughthe keeper E.

The. tug is then in a complete form and ready for use. It will thus beseen that the sides of the tug loop are formed of double strap sections,and the buckle passes through the said strap three times, thus formingnot only a strong and secure manner of connecting the tug strap, butalsoproviding a very simple means for detachably holding the same, Wherebyit can be quickly reversed when desired.

When adjusted and arranged as shown in Fig. 2 should the hearing facesl0 lO of the strap become Worn by friction such faces can be removedfrom Contact with the thill by reversing the strap, t'. e. by detachingthe same, bringing the end 2 into engagement with the buckle first, andfolding as before; and when so folded the worn faceslO l0 will be at theoutside as indicated in Fig.

It is obvious that by forming a tug of a single strap and detachablyconnecting the same in the manner stated, a much longer use of the tugstrap is attained, and by making the side Walls of the tug of doublesections, the inner or bearing face is reinforced and much relieved fromstrain.

It will be perceived that the tug strap is ad- IOO justable in length toadapt it for any size of thill.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In a shaft tug, in combination, a strap having holes at each end andat a pointbetween such ends, a link having opposite eye portions, and abuckle, said straps connected to the buckle tongue at one end, bent toform opposite loops, to which the link eyes are connected the saidbuckle tongue passing th rough the center, and the free end holes in thesaid strap, substantially as shown and described.

2. In a shaft tug, the combination with the skirt buckle, and the girthlink, of a strap having holes at each end, and centrally, Whereby it canbe secured to the buckle tongue at three points, at the ends, andcentrally, to form loop portions, said loop portions being connected tothe girth link, and wherebysuch strap is adapted for a detachable andreverslble connection with such buckle and link all substantially as andfor the purposes described.

3. In a shaft tug, the combination with the buckle D, and the girth linkB, of the strap A, having holes at each end,and centrally, and thekeeperE having an apertured tongue e, adapted to fit over the buckletongue, said strap A connected at its ends, and centrally, to thebuckle, and its loop to the link B, and passed with one of its sectionsthrough the keeper E, all arranged substantially as in the manner andfor the purposes described.
